OPERATOR FOR WINDOWS Filed Dec. 31, 1928 2 Sheets-Sheet 2 INVENTOR Patented May 3, 1932 UNITED STATES PATENT OFFICE CLYDE W. KELLY, OF DETROIT, MICHIGAN, ASSIGNOR T0 DETROIT STEEL PRODUCTS COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN OPERATOR FOR WINDOWS Application, filed Dec mber 81, 1928. Serial No. 329,533.

The invention relates to operators for windows and refers more particularly to operators for screened windows, in which the screens are located at the inner sides of the windows. One of the objects of the invention is to provide means for closing the open ing in the screen providing for the passage of the means for actuating the ventilator. Another object is to provide a closure mem her for the screen opening movable to allow the ventilator actuating means to assume various angular positions. Further objects of the invention reside in the novel features of construction of the operator and its support and the combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 is an interior side elevation of a window embodying my invention;

Figure 2 is a cross section on the line 22 of Figure 1;

Figure 3 is a cross section on the line 33 of Figure 2;

Figure 4 is an interior side elevation of a portion of the window with the operator removed;

Figure 5 is a view similar to Figure 2, showing a modified construction;

Figure 6 is a cross section on the line 66 of Figure 5;

Figure 7 is a view similar to Figure 4, showing a modified construction.

The invention is particularly ap licable to windows having swinging ventilators, such as casement windows, which latter is shown in the present instance. 1 is the frame having an opening and 2 is the ventilator tor the opening, this ventilator being pivotally mounted at one side upon a side bar of the frame. 3 is the screen located at the inner side of the frame and detachably held thereagainst by suitable means, such as the clips 1-, upon the frame engaging the top and bottom bars of the screen frame. The bottom bar 5 of the screen frame is formed with the opening 6 therethrough for the passage of the means for actuating the ventilator.

The ventilator operator includes the support 7 and the rod 8 slidably engaging the support and having the curved end 9 connected to the ventilator by means of the bracket 10 rigidly secured to the inner side of the bar of the ventilator and extending inwardly therefrom. The connection between the rod and bracket is formed by the pivot 11, which extends through a portion of the curved end reduced in thickness so that the lower face of the bracket is substantially flush with the remaining portion of the rod. 12 is a bracket rigidly secured to the inner side of the bottom bar of the frame 1 and having a' lateral inwardly extending portion 13 spaced below the bottom screen bar 5 and an upwardly extending portion 14- extending parallel to and spaced slightly from the innor side of the bottom screen bar. The upwardly extending portion 14 is provided with the longitudinally extending elongated opening 15 havina the notch 16 at its lower edge. 17 is a laterally extending plate passing through the notch 16 and rigidly secured to the lateral portion 13 of the bracket 12, the inner end of this plate being pivotally connected to the rod support 7 at 18 for supportinn the same.

With the arrangement as thus far described, the ventilator actuating rod 8 may extend substantially parallel to the screen when the ventilator is in closed position, as shown particularly in Figure 3. By swinging the actuating rod and its support 7 about the pivot 19 leverage is provided for initially opening the ventilator, after which the rod may be longitudinally moved in its sup port to continue the opening of theventilator, the rod and support during this opening movement continuing to swing about the pivot. The elongated opening 15 in the upwardly extending portion 14 of the bracket- 12 and also the elongated opening 6 in the bottom screen bar readily permit this angular movement.

For the purpose of closing the opening 6 in the bottom screen bar and also the opening 15 in the bracket 12, I have provided the closure member 20, which is longitudinally slidable upon the bracket 12. This closure mem her is preferably formed of sheet metal and has the opening 21 therethrough for the pas- 5 tion lat of the bracket 12 to assist in supporting? and guiding the closure member. The closure member is also preferably provided with the inwardly extending flanges 22 at the upper and lower edgesof the opening 21- and extending into the opening 15 of the upwardly extending portion of the bracket 12 to assist in guiding the closuremember. The closure member, being slidable longitudinally upon the bracket, permits angular movement of the actuating rod 8 and at the same time closes" the opening 6 in the bottom screen bar.

In the modification shown in Figures 5,. 6 and 7, the arrangement of parts is very similar with the except? on ofthe support for the ventilatoroperator and the means for guiding, the closure member for the opening in the bottom screen bar. As shown, the support for the ventilator operator comprises the bracket 23', which is rigidly secured to the inner side of'the bottom b'arof the frame 1'." and has the outer laterally extending por tion' 24 and the innerlaterally extending portion'25, the latter being elevated to a height above that of the. former'and be ngpivotally connectedto the operator rod support 7. 26 isa plate preferably formed of sheet metal and having'a depending portion 27 clamped between the inner side of the bottom bar of the frame 1' and the adjacent portion of the bracket 23, a portion 28 supported upon the laterally extending portion 24: and an upwardly extending portion 29 extending par.- allel to but spaced from the inner. sideof the bottom bar 5 of the screen. This plate has depending beads 30 with spaced side walls at opposite ends of the laterally extending portion 24-. The upwardly extending, portion 29 ofthe plate is formed with the longitudinally extending elongated opening 31 providing for the passage of the operator rod and has its upper portion bent outwardly and then downwardly to form. .a downwardly opening channel. Theclo'sure member is inthe nature of a sheet metal plate 32 having an opening 33 for the. passageof. the operator rod and having at the ends of its lower edge the projections The. upper .edgeof this closure member slidably engages in the downwardly open ng channel tormed in the upper edge of the upwardly extending portion 2.9 and the projections 34- of this closure member slidably engage in. the beads 30. It will thus be seen that this closure member closes the opening in the bottom screen bar and incidentally the opening in its guide.

From the above description it will be seen that I have provided an operator for actuating the ventilator of a window which is so constructed that the motion of its parts connected to the ventilator is substantially continuous and easily eifected during both the opening and closing of the ventilator. It will also be seen that I have provided a simple construction of closure for the opening in the screen through which the operator rod extends, this closure providing for angular movement of the operator rod.
